For this particular recipe, I started with French bread and a dozen eggs. (Makes sense for breakfast, right?)

From there I went with traditional breakfast flavors, including ham, cheddar cheese, and chopped peppers. For even more flavor, I added dijon mustard, garlic powder, salt, pepper, and thyme.

Ingredients

Instructions

  • Begin by preheating your oven to 350 degrees F. Spray a 9x13-inch baking dish with cooking spray. Fill with the bread, ham, peppers, and cheese. Mix to evenly combine.
  • In a large bowl, whisk together the eggs, milk, Dijon mustard, garlic powder, fresh thyme, salt, and pepper. Pour this mixture on top of the bread mixture. Gently press down the bread with a spoon. Sprinkle with shredded Parmesan cheese.
  • Bake 50-55 minutes until the eggs are cooked through. Cover the pan with aluminum foil if the top begins to brown too quickly. (If preparing the casserole in advance, cover the baking dish with aluminum foil and refrigerate overnight. Bake as directed.)
  • Garnish with fresh thyme and slice to serve.

  1. Each Christmas I make an overnight casserole for Christmas morning. I decided to try your recipe. My husband said this was the best one yet!! I agree! This will be my go to casserole each year Christmas!! So delicious!! Thank you for the wonderful recipe! I love your site also, I have followed you for a while now. (and you are just adorable) Happy New Year!!! Hugs!!

  2. This recipe seems like a great opportunity to empty out the fridge using ingredients that may expire soon, right? I love it! I especially love that you can prep it the night before and just bake it in the morning…so I could throw it in the oven, take my dogs for a walk, and when we come back STARVING, breakfast.is done! Ha!
    I’m keeping this recipe in mind for the holidays as well.
    Thanks for sharing, Michael!

  3. I just discovered your recipe when you reposted it and made it last week. Since there are a couple of vegetarians in my family I left out the ham and added in some mushrooms and lightly cooked fresh spinach; kept everything else the same. It was delicious! Wonderful to serve on these cold January mornings.

  4. This recipe was a complete sensation!! It was a total hit! Incredibly delicious!! Made the overnight version. Used green peppers only. Thank you so very much for sharing! Readers, you will love this recipe!

  5. I’ve made this dish before, except I made mine sweeter, more like a bread pudding (same basic recipe). I used the bread (any white or whole wheat), eggs, milk and cinnamon. I layer in blueberries. Great with syrup and sausage on the side. For years, this was my go-to for Christmas morning.
